This phenomenon is modeled by a scalar field and a tensor field in Brans-Dicke theory. The Hulse-Taylor binary pulsar emits its namesake waves, the subject of the LIGO study. In QFT, it is mediated by an uncharged, massless, spin-2 particle, but that approach fails at the Planck scale. Using a torsion balance, Henry Cavendish measured its characteristic constant, which is the proportionality constant in an inverse-square law named for Newton. It is the weakest fundamental force and its potential energy is given as mgh, where g = 9.8 meters per second squared. For 10 points, name this attractive force which pulls objects towards the center of the earth.
